DIODES INC. BCR420UFD7 LED Driver Regulator

The BCR420UFD and BCR421UFD are integrated linear LED constant current regulators designed for driving low-current LEDs efficiently. These devices operate by controlling the LED current with internal or external resistors, supporting currents up to 350mA and reducing PCB area by eliminating external components such as inductors and switching diodes. Suitable for applications like signage, decorative lighting, retail displays, and architectural lighting, they feature a compact U-DFN2020-6 package, low thermal resistance, and are RoHS compliant. Both models include PWM control for dimming and protection features against reverse polarity and overcurrent conditions.
